Myrtle Avenue (BMT Jamaica Line) - Lower Level

Lower Level

This elevated station, opened on June 25, 1888, has three tracks and two island platforms. The J and Z trains use the middle track for peak-direction express service on weekdays while the M train uses it as a terminal track for its late night and weekend shuttle service to Middle Village – Metropolitan Avenue. The rest of the time, both the J and M trains are on the local tracks.

Both platforms have brown canopies with green support columns and frames for their entire length except for a small section at either ends. The station signs are in the standard black plates in white lettering.

This station has an elevated station house to the west underneath the skeletal remains of the BMT Myrtle Avenue Line. Two staircases from each platform go down to an elevated crossunder, where a shorter staircase on the Queens-bound side leads to the station house's waiting area. Outside the turnstile bank, there is a token booth and two staircases going down to either western corners of Myrtle Avenue and Broadway.

The 1999 artwork here is called Jammin' Under the El by Verna Art. It consists of stained glass windows on the platforms' sign structures as well as the station house depicting various scenes related to music.

North of this station, an "S" curve connects the BMT Jamaica Line to the Myrtle Avenue Line, used by the M train. This is one of the few remaining level junctions in the subway as well as one of the few places on revenue tracks with slip switches.
